| Oxide Cathode |
| |
| This cathode is available in both the modular construction (shown in the photograph) and in other constructions. It is used in a wide range of applications in all types of cathode ray tubes (CRT).
It has the following key features:
-
Long lifetimes for loadings up to 2.2 A/cm2 (>20,000 hours) with a patented emitting element of double carbonate spray layer on a nickel substrate
-
Fast warm up time in a suspended cathode structure with excellent thermal stability
-
Low power consumption (0.65 W) with advanced design
-
Improved quality control and production yield from direct mounting structure into electron gun by integrated cathode module incorporating heater and sleeve
-
Wide application for wide screen, real flat and curved colour picture tube
